They'll eventually be dragged into the future by requirement, 1GbE is already standard on most equipment, with 2.5GbE and 1+gbit wifi becoming more common on consumer equipment. The increasing reliance of on-demand delivery of various forms of content, from multimedia to gaming, is already pushing 100Mbps connections to where 10Mbps connections were less than 5 years ago.

I think its worth choosing fiber in a new deployment, at least at the distribution level (between floors, or zones of the home). Most new computers come with ultra fast solid state storage, so even between systems on a local network, 10GbE speeds could be useful.

With the way the price of copper is going, and how much less efficient rj45/copper chipsets are compared to optical, I wouldn't be surprised if we see a shift to optical as a replacement to rj45 in the next decade.
